Call for sewing advice!

My son in a Swaddlebees cloth diaper when he was 11 months old.
We are a cloth diapering family. I had never intended on cloth diapering my kids, but when my oldest was 10 months old, I read a post from an old high school friend on her reasons for using cloth diapers. What she said really struck a chord with me and the mister and I set out to learn all we could about modern cloth diapers.

After much research, we felt like pocket diapers would be the best fit for our family. I bought a sampler of different brands to see what I liked. Ultimately, we settled on BumGenius and used those on his little tushy until he quite literally outgrew them. When his little sister was born, we bought a handful of newborn Kissaluvs fitted diapers to try right after she was born. Unfortunately, I didn't feel comfortable with them and couldn't get them to not leak (I'm sure I didn't put the cover on right). So we returned them and ordered more BumGenius since we liked them so much for her brother.

Here's where the call for sewing advice comes in. I really want to try my hand at making some pocket cloth diapers. But, I'm a little wary that they won't work as well as the BumGenius diapers have. I know there are moms out there who make their own diapers and I know they've worked for their kiddos. Do any of you know of any good patterns or tutorials out there for making good (read leak-proof) cloth diapers? I prefer pocket diapers, but if you know of any other patterns, let me know.
